Is This a True Story?

Hey all,

whilst fishing on saturday had an old bloke who said hes been a local for nearly all his life. he started telling me a story, but i dont know if it is true, it sounds convincing though. Anyways the story is that at hillarys marina north wall you can see some big antenna and lights well aparrently there is a drain that comes all the way from ballajura (spelling) that pumps dirty polluted water into the area. When building the pipe they were meant to extend the pipe all the way past little island where the current would move it away, though the only made it 200m long. He was also saying that the water they were pumping out contained a high percentage of nitrogen and that this changes the fish that live around the area as well as making all that cabbage weed on the rocks.There was also another drain built by ocean reef harbour that was meant to be the same as hillarys and extend 2km out but they cut it short 200m making it 1.8km and this making the the polluted water staying in the area and not being swept out.

 

But what i found most intresting about the story is that the man telling the story said he always loves his crayfish and is always targetting them by diving and pots. what he was saying is that all the crayfish between Two rocks south to Trigg (I think) have a unique black spot on their back.

 

 

Just wanting to know everyones opinion, as i find this story very convincing.

 

Cheers,

Eric

Black spot

Mon, 2010-08-16 21:13

Not sure but I think female crayfish have what is called a "Tar Spot" that is actually sperm from the males. They just have to scrape it a bit and they are fertilized...like bogan girls.....

mate i reckon he quite possibly just enjoyed somebody wanting to listen! think u should take that with a pinch of salt, considering crays move vast distances

Haha i dont know squat about crays...

but i forgot to add this in...

he was saying that if oyu go to any other southern beach and catch a herring then catch a herring at hillarys north wall, cook them the same on the barbe and they will taste completely different. The Hillarys north wall being SH**.

I dunno which southern beaches

Tue, 2010-08-17 06:43

But if he is talking about herring from near woodmans pt, he could have some truth in the taste being different.  The lime crushing facility on the west end of woodman pt has been clouding the water with lime around there for plenty of years.

Sewer outfall at

Mon, 2010-08-16 21:30

Sewer outfall at hillarys???? Not that I can see.

Have a look here http://www.nearmap.com/

You can see the twin outlets at ocean reef, the outlet at swanbourne...... nothing at hillarys

Sewage

Mon, 2010-08-16 22:05

No untreated sewage is released into the ocean except for some floaties that come from animals etc. and the occasional one that finds its way down a storm water drain. That one missed the toilet by the way or they guy was in such a hurry he could not make it. Anyway, treated sewage water, and I know you do not want to here this, is actually drinkable. In some contries treated sewage water is actually recycled and recovered for domestic purposes. Wink Everything in life is effected by the nirtogen cycle. Nature sorts it all out for us unless we rape nature by giving back more nasty stuff than nature deserves.

About the nitrogen mentioned - 70 % of the atmosphere is nitrogen and that's the building block for plants. Nitrites (Process of Nitrification and denitrification) form in raw sewage by means of bacteriological break down and it will kill fish very quickly.  This is what causes 90% of fish deaths in home aquariums because it is not converted to Nitrates that can be taklen up by plants for food. There are places in the world where they pump sewage into the ocean, it eventually breaks down completely as a result of the natural process (Nirtrogen cycle) but it can do heaps of damage because it uses up oll the free oxygen in the water for the breakdown process.

I will stop now before I get carried away.

Cheers

Have to correct this in case

Tue, 2010-08-17 19:48

Have to correct this in case anyone reads my entire post above. Made a typo as the 0 is next to the 9 on the keys. Atmosphere has 79% nitrogen and not 70% as I said above. Now I can sleep knowing I told the truth. hahahaha,

Cheers

I'm not a chemist but

Mon, 2010-08-16 23:29

I do get what you are saying JR JetSki... I have been involved in the water/wastewater industry for 30+ years (including ocean sampling of the outfalls but that was just so I could get out on a boat Wink).

Not only has it less turbidity, "gremlins" and is possibly more drinkable than potable water but you will find that in the future you will be drinking it.

I have recently and still am involved in setting up groundwater replenishment trials using treated effluent from sewerage treatment plants, treated bore water and even dams water to enable the groundwater table to have the effluent or treated water injected into the aquifer and filter through the limestone etc and be pumped out and treated via the several/hundreds of bores in the metro area.

The chemicals added to our water system would be more of a worry than recycling treated effluent.

If the above mentioned trials prove unsuccessful they should use the treated effluent for watering local parks and ovals like country shires do.

PS DieHard.... Sorry to hijack your thrad but the old guy was telling you a story.

Will stop now as I a have always believed treated effluent should have been reticulated for parks/ovals instead of pumped out to the ocean.

Fully agree with you dagree

Tue, 2010-08-17 08:08

And with a scientific background and the knowledge that without water we are all useless. I like the idea of pumping treated water into the sea, then desalinating it back for us to drink--- NOT.

I once lived on the Harvey river with a spike in the river for water. Pumped up to the house and yum. One day whilst marroning upstream came across a dead bogged rotten cow in the river, about 12m up from the spike. Shat myself as we have been drinking the water and I had a wife and 2 kids in the house. Then logic kicked in. The water was flowing fast from Wellinton Dam and this pure aerated water acts like a Antibiotic.

Decided to check however, bying some bottled water for the missus and kids, but I drank it out of the river. In flowing water 2 m away from the carcass the water is very safe to drink. This was from a scientist at the WaterCorp then.

And cant see why we dont use recycled water in all ways. We are always short and looking for H2O. Nature will purify the water perfectly, and as I see it water we drink has been through this cycle for eons, and we arent sick from it.

Every drop has been through the gut of something sometime, so is waste water. I think pansie humans have to get over the idea and get on with using it for the benefit of us all.

JMO and opening a can of worms.

I fully agree with you

I fully agree with you dagree. Have also been involved in RO application where RO permeate gets pumped into the ground to keep saline water out of the drinking bores. Interesting and very expensive processes.

Sorry guys, water is my life, has been for 32 years. Cant live without it can we??? And I learn something new about water every day of my life. Amazing stuff this clear liquid.

cheers

Naff all wrong

Tue, 2010-08-17 08:19

with treated waste water - i did a lot of work over the years with the Water Corp involving treated waste water - it is the way of the future. We tested water for over a year from some bores right next to the effluent ponds at Halls Head - clean as a whistle - and just think, your next beer has to contain water molecules that were once urine - even if it was millions of years ago.

drains

Tue, 2010-08-17 11:02

I don't know about black spots,but i did put up a post early this year about those drains at hillarys,when I swim with my medic alert bracelet it turns brownish right away,that dosen't happen at other beaches.on calm days there is alwallys an odor and slick like stuff in that corner beach
